RICHARD LAMB, OF ARROWSMITI-I, ILLINOIS.

. CEMENT-FINISHING TOOL.

a ea e filed July 21, 1916. Serial Nb. 110,574.

To all whom it may concern Be it known that I, RICHARD R. LAMB a citizen of the United States, residing at Arrowsmith, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Cement-Finishing Tools, of which the following is a specification.

This invention relates to certain new and useful improvements in cement finishing tools.

The primary object of this invention resides in the provision of a cement finishing tool which will be of simple construction, may be readily adjusted with the handle extended at any desired angle andwhich will be highly efficient in use.

Another object of the invention resides in the provision of a means whereby a single connection may be formed between the same and the handle and the latter readily adjusted to any desired angle.

A further object of the invention resides in the provision of a joint or connection between the tool and the handle whereby a single long handle may be employed and removably connected with any one of the tools.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings forming a part of this application and in which like-designating characters refer to corresponding parts throughout the several views, in which Figure l. is an elevation partly in section, showing the handle applied to one of the cement finishing tools.

Fig. 2 is a plan View of another cement finishing tool constructed to receive my improved form of handle.

Fig. 3 is a plan view of a portion of another form of cementfinishing tool adapted to receive my new form of handle.

Fig. 4 is a longitudinal section through the tool part shown in Fig. 3.

Fig. 5 is an enlarged elevation of a further form of cement finishing tool.

Fig. 6 is a side elevation of the form of Specification of Letters Patent.

tool shown in Fig. 5 with the handle applied thereto. I p

Fiig. 7 is a plan view of a corner finishing too i Fig. 8 is a sectional view through the same substantially on the plane of line 88 of Fig. 7.

Fig. 9 is a plan view of another form of corner finishing tool adapted to receive my improved form of handle, and

Fig. 10 is a sectional view through the tool shown in Fig. 9, substantially on the plane of line 1010 of Fig. 9.

Referring more in detail to the drawings, 1 designates the core of the handle which may be formed of any suitable material and may either be solid as shown or hollow as preferred. Clamped upon opposite sides of the core 1, are the longitudinally extending connecting members :2 which are preferably of semi-circular form in cross section, said connecting members being clamped upon the core 1 by suitable bolts 3, one or more of which may be extended through the core 1, said screws 3 having suitable heads 4 formed upon one end, while thumb nuts 5 or the like, are threaded upon their opposite ends. The lower ends of the connecting members 2 are extended past the lower end of the core 1 and provided with concaved recesses 6 in their inner faces to receive the spherical members 7 formed on a stem 8 which is secured in any suitable manner in a socket 9 formed upon the upper face of the cement finishing tool 10. It will be understood that the extended end of each connecting member 2, is provided with a central oil or lubricantreceiving opening 11, whereby suitable lubricant may be supplied to the spherical member 3 to reduce friction to the minimum.

l/Vhile I have not shown the handle applied to all of the different cement finishing tools shown in the drawings, it will be evident that the handle may be connected to each in the same manner and by loosening the nut 5 upon the lowermost bolt 8, the handle may be readily turned to any angle desired with respect to the upper face of the tool 10 and then securely locked in adjusted position by again tightening the nut 5.

I/Vhile the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor 7 bracing opposite sides of said handle adjacent its lower end, said'clamping members having their laterally curved edges-extending in spaced parallelism and" having their lower ends extending beyond the lower end .vided on their inner faces with'opposed concaved recesses adapted to be oppositely engaged withsaid spherical head, a fastening bolt passing through said handle and the upper ends of said clamping members,

and an adjusting bolt passing through the lower ends of said clamping'members and engaged with the lower endof said handle.

In testimony whereof I affix my signature in presence of two Witnesses. RICHARD R. LAMB.
